Doctor Feedback

Trusted by Pediatric Dentists

Hear how clinicians are using BioFlx to deliver esthetic posterior restorations with a preparation and placement experience that feels familiar.

Dr. Paul Bahn

“BioFlx allows for an esthetic posterior crown with less technique sensitivity and conservative tooth preparation.”

Paul Bahn, DMD Pediatric Dental Associates
Dr. William Waggoner

“I love the ease of placement and durability of stainless steel crowns, but after 40 years practicing pediatric dentistry, I'm super excited to have a tooth-colored crown for primary teeth that will be as easy to prepare and fit as a stainless steel crown.”
